thank you for the suggested cam, but im really wanting a roller cam for longevity and less friction. I did look into one with a longer duration then the ones I mention. Its a 222/228 @.050 .510/.510 lift 110 LSA rpm range about 2000-6100. With aluminum heads, dished piston, .060 head gasket (to get about .035 quench), and the cam I just mentioned I get a static compression ratio of 9.764 and dynamic of 8.484. How does that sound for pump gas?

That cam would do fine on pump gas with 10:1 CR, quench and aluminum heads. Now adays with there being good, hi-zinc oils on the market made for us muscle car guys I am more comfortable with a flat tappet cam than a roller cam with lifters that have bearings and roller wheels. Not to mention cam buttons and bronze oil drive gears.

Main reason Im pushing for roller cam is cause of the break in on first start up. I know your suppose to keep it reved pretty high for a half hour. Since its going to be fuel injected with the FAST EZ-EFI it has to learn to run. I dont want to mess anything up and dont want to flatten the lobes.

Break it in with a carb. Putting an efi system on mine and I'm doing that. Probably easier on the rings than an overly rich universal efi system trying to tune itself while the rings seat.

I'd only run a roller like that in a SB if starting with a magnum engine that I could just have the stock roller cam reground.

I suppose I could use the carb to break it in, problem being is im not even sure the carb was tuned right before I took it off. I can set my target air fuel ration on the ecu to more on the leaner side. It uses a wide band o2 to read mixture and adjusts from there.

For the EFI break-in triple or quadruple check your setup. Injector size, displacement, closed loop parameters ect. Also I'd open up the "closed loop correction limits". With a good oxygen sensor 25% isn't too much for start-up.
